Trial figures provided by the two companies suggest that Pfizer has the more effective pill, but they have not yet offered full data. It did not provide figures regarding patients getting the pill within three days of onset. Pfizer said about 20% of patients who received either the pill or a placebo experienced adverse events, mostly mild. Drugs in the same class as Merck’s pill have been linked to birth defects in animal studies. Britain has secured 250,000 courses of Pfizer’s drug, but prices for the British contracts have not been made public.
